Abstract
The invention particularly discloses a slant hole drilling clamp of an output shaft part of an automobile gear box, and solves the problems that work pieces are easy to damage and drilling precision is difficult to guarantee when a slant hole of an output shaft part of the conventional automobile gear box is machined. The clamp comprises a base; a hydraulic rod perpendicular to an inclined plane of the base is arranged in the base; a dividing disc is arranged on the inclined plane of the base; a lower connecting disc is fixed on the dividing disc; an upper connecting disc is fixed on the lower connecting disc; a positioning pin penetrates through the upper end surface of the upper connecting disc; a spring sleeve is sleeved at the upper part of the upper connecting disc; a pull disc is sleeved at the lower part of the upper connecting disc; the pull disc is connected with the hydraulic rod; a pull claw is fixed at the upper end of the pull disc; and a gap is formed between a lower step surface on the outer side of the pull disc and the upper end surface of the lower connecting disc. The clamp adopts one positioning to realize circumferential positioning, and ensures that the work pieces are not deviated when suffering strong cutting force by adding a hydraulic clamping mechanism, and has the advantages that the clamp is convenient, time-saving and labor-saving to operate.
Description
Technical field
The present invention relates to the processing of automobile gearbox output shaft part and use auxiliary mould, be specially a kind of automobile gearbox output shaft part clamp for drilling slant hole.
Background technology
one end of automobile gearbox output shaft part is disc-shaped structure, and uniformly take its axle center as the center of circle on this end face have five circular holes, and need to be drilled with inclined hole on the inner cylinder face of circular hole, the fixture that the tradition rat holing adopts is to pass through axial location, manually clam member guarantees that the workpiece that tilts is not offset, circumferencial direction adopts five alignment pins to control the rotation of part, on alignment pin, drill bushing is housed simultaneously, drill bit is played the effect of guiding, in process, because boring is the deep hole machining of diameter 5mm, and the drill bit tip is not in the plane, usually drill bit is broken and cause the useless problem of damaging of workpiece in workpiece, simultaneously, borehole accuracy is difficult to guarantee.
Summary of the invention
The problem that the present invention easily causes the useless damage of workpiece and borehole accuracy to be difficult to guarantee while in order to solve, having automobile gearbox output shaft part tooling processing inclined now, provide a kind of automobile gearbox output shaft part clamp for drilling slant hole.
the present invention adopts following technical scheme to realize: automobile gearbox output shaft part clamp for drilling slant hole, comprise the base that is fixed on the lathe working face, be provided with the hydraulic stem vertical with its inclined-plane in base, and the axis take hydraulic stem on the inclined-plane of base is provided with index dial as the center of circle, be fixed with lower terminal pad on index dial, be fixed with terminal pad on lower terminal pad, upper terminal pad upper surface is installed with alignment pin, upper terminal pad top has the diminishing taper endoporus of diameter from top to down, and the taper endoporus inner sleeve of upper terminal pad has the spring housing that is mated, upper terminal pad bottom has cylindrical bore, and the cylindrical bore inner sleeve of upper terminal pad has the pulling plate that is mated, pulling plate is passed lower terminal pad and is connected with hydraulic stem, the pulling plate upper end is fixed with the pulling claw that is stuck on the spring housing lateral wall, and leave gap between the outside downstairs face of the pulling plate above lower terminal pad and lower terminal pad upper surface.
Carry out inclined hole and add man-hour, the machining hole of workpiece (being automobile gearbox output shaft part) is put into spring housing to the position of living alignment pin, realize the circumferential registration of workpiece by a location, place; Drive hydraulic stem by hydraulic mechanism this moment and shrink, pulling claw drives spring housing and moves down, and under the effect of upper terminal pad taper endoporus, the spring housing internal diameter dwindles, and workpiece is stepped up, and realizes the workpiece axial location; The contraction scope of spring housing diameter has been limited in gap between pulling plate cascaded surface and lower terminal pad upper surface, the problem that easily causes the useless damage of workpiece and borehole accuracy to be difficult to guarantee while having overcome existing automobile gearbox output shaft part tooling processing inclined.
Upper terminal pad is fixed with dust cover on upper surface, has on dust cover and wears workpiece hole, prevents that scrap iron from splashing is to fixture inside.
Reasonable in design of the present invention is reliable, realize that by rotation-indexing table workpiece five holes add the requirement of the automatic rotation in man-hour, clamped one time can be processed five holes, and workpiece adopts place's alignment pin to realize circumferential registration, can remove alignment pin everywhere, reduce the location replication problem, very firm, and increasing Hydraulic Clamping Mechanism guarantees that workpiece adds and is subject to strong cutting force man-hour and can be offset, improved well the hole site precision, the rate 50% of reducing the number of rejects and seconds, have advantages of simple operation and time saving and energy saving, and working (machining) efficiency has improved 30%.
